SPECIFICATION forming' part of Letters Patent No. 717,826, dated January190g.

Application Jfiled May Sl, 1902. Serial No. 109,766. (No model.)

To @ZZ whom, t may concern.:

Be it known that l, CHARLES W. ELL'Is, a citizen of the United States',residing at lndianapolis, in the countyof Marion and Statev of Indiana,have invented certain new and useful Improvements in Packers, of whichthe following is a specification.

My invention consists in certain improvements in packers, and has forits objecta means for packing allr kinds of fluffy homogeneous material,such as bran, iiakes, dto.

The object consists, further, in providing a packer having a movableplatform lwhich carries a plate mounted in ways to which the casingwhich incluses the sack is secured, a cylinder through which thematerial is fed into the sack, a reciprocating plunger working withinsaid cylinder, and a chute connecting with the cylinder through whichthe material is fed, the said chute being provided with a valve which isoperated by a crankarm secured to the shaft to which the valve issecured, the said crank-arm having an upright pivotally secured thereto,which is formed into a hook on the upper end and which hook engages withan arm on the plunger-beam, and through which construction analternating movement is imparted to the valve, thus discharging thematerial to be packed into the cylinder in an alternating manner.

There are other features, and the construction and arrangement of theseveral parts will he hereinafter more particularly described, and thenpointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof andon which similar numerals of reference indicate similar parts, Figure 1is a front elevation of my packer and shows the movable platform in itslowest position. Fig. 2 is a side elevation of the construction shown inFig. l. Fig. 3 is a central vertical section of the pac ker, on aconsiderably-enlarged scale, and shows the platform raised andenveloping the cylinder, in this figure the uppermost or drivingmechanism of the packer being broken away. Fig. a is a side elevation ofthe lower portion of the packer with the platform raised and alsoshowing the manner in whichthe movable platform actuates the mechanismfor operating the valve in the chute.

Fig. 5 is a horizontal sectional vieur of the packer and shows theplatform in plan view. This figure also shows how the casing isadjustably secured to 'said platform. Fig. 6 is a fragmentary detail, onan enlarged scale, of the vise-shaped clutch mechanism which regulatesthe downward movement of the platform, as well as determining thepressure on the material by the plunger; and Fig. is a fragmentarydetail in elevation of the plat= form and shows the manner of insertingthe adjustable block that forms the base when packing material intobarrels.

In the drawings, 1 represents the uprights of the framework of thepacker which forms the guide for the platform.

2 is the movable platform. The platform 2 is provided at each end with astandard 3, which stands vertically with and against the uprights 1 ofthe frame. The standards 3 are provided with the yokes 4, which extendacross the face of the uprights 1 and keep the two parts in alinement.The yokes also form a bearing for the vertical rods 5, which are securedto the platform 2 at the bottom and have an eye at the top, to which thechains 6 are secured. The chains 6 extend upward and engage with thegrooved` wheels 7 by means of the lugs 8 and hooks 9.

The packer is provided at each side with one of the grooved wheels 7,which are mounted on the transverse shaft '10, suitably secured inbearings in the framework of the packer. On each side of the packer andmounted on the transverse shaft 10 and adjacent to the grooved wheels 7are the balance- Wheels 11,having a grooved periphery, which form a seatfor the cables 12. Each of the wheels 11 has a cable 12 secured thereto,each of which has a balance-weight 13 secured to the suspended end. Thebalance- Wheeis 11 are each provided with a frictionclutch whichregulates the downward movement of the platform, and on the release ofthe said clutches, which will be hereinafter described, and under thetension of the weights 13, as previously described, the platform 2 israised. The movement of the platform also regulates the amount ofcompression exerted by the plunger on the material being packed. Eachfriction-clutch is formed like a vice composed of the jaws 14.

and 15, between which the wheels pass. The jaws 14 and 15 of theclutches are mounted on the threaded stud-shafts 16, each of which issecured to a suitable base fixed to the framework of the packer. Acoil-spring 17 encircles each of the shafts 16 between the jaws of theclutches. The springs have a tendency to relax the pressure of the jawson the wheels 11 when the lower ends of the jaws are actuated. Theshafts 1.6 are provided with the hand-wheels 18 and 19, one of whichregulates the longitudinal movement of the jaws, while the other acts asa jamnut. The lower ends of the jaws 14 are provided with groovedfriction-wheels 20, while the jaws 15 carry the cams 21, which engagewith said friction-wheels. The cams 21 are mounted on the shafts 22,which extend to the rear of the framework 1. The shafts 22 have thecrank-arms 23 secured to the rear ends thereof and which are connectedtogether by the connecting-rod 24. One of the shafts 22 extends forwardand has the crankarm or hand-lever 25 secured thereto,so that onactuating the hand-lever 25 the shafts 22 and clutches are operated simultaneously through the connecting-rod 24. When the wheels 11 arereleased from the clutches, the weights 13 cause lthe platform to rise.To limit the upward movement of the platform, I secure the stops 28,having a flexible cushion, to the side of the nprights 1 of theframework of the packer. When the platform rises, it envelops thevertical cylinder 27, which is secured at its upper end in the frame 1.The platform rises until the floor thereof is approximately twelveinches from the lower end of the cylinder 27, which provides ample roomfor the first discharge of the material, and hence no descent of theplatform takes place on the first compression. The upper end of thecylinder 27 is closed. A plungerbeam 29 passes through the cover of thecylindex' and has the plunger-head 30 secured thereto, which compressesthe material. The upper end of the plunger-beam 29 has the guide-strips31 secured thereto, which strips engage with the xed guide 32, whichguide prevents any lateral movement of t-he upper end of said beam. Apitman 33 is pivotally secured to the beam 29, which pitman is securedto the crank-arm 34 on the shaft 35, and through the shaft 35,gear-wheels 36 37, and the pulley 38 the plu nger-beam 29 is operated.

A chute 39 connects with the cylinder 27, through which the material isfed. The chute 39 is provided with a valve 40, mounted on the transverseshaft 41. The shaft 41 has a crank-arm 42 secured to each end. The arm42 on one end of the shaft carries the weight 43, (see Fig. 1,) whichinsures the closing of the valve. The valve 40 is actuated by connectingthe upright 44 to one of the crankarms 42. The upright 44 has a hook 45formed on the upper end thereof, which stands in the path of and engageswith an arm 46, secured to the plunger-beam 29. The arm 46 on theplunger-beam comes into contact with the hook 45 on each upward strokeof the plunger, which contact opens the valve 40' in the chute. Theupright 44 is made in two parts and can be adjusted so that the hookwill engage with the arm 46 at a desired point, and thus determines notonly the throw of the valve 40, but regulates the amount of thedischarge. It will be readily seen that through this construction I canprocure a discharge of various amounts, which is one of the mainfeatures of this invention. I may also state that the contact of the arm46 on the plungerbeam and the hook 45 is near the terminus of the upwardstroke of the plunger-beam, the valve 40 opening when the plunger-beamis above the egress of the chute 39.

The upright 44 passes through a horizontal sliding plate 48, which plateis mounted in ways cut in rthe sides of the box or trough construction47, which is fixed. (See Fig. 4.) The sliding plate 48 when actuated,and which will be hereinafter described, moves the upright 44 into orout of the path of the arm 46 on the plunger-beam. The upright 44normally stands in the path of the arm 46 under the tension of thespring 49 during the time the valve 40 is being operated, and only whenthe upright 44 is thrown out of contact with the arm 46 is the valve 40at rest, the reason for which will be hereinafter fully described.

It willbe seen by examining Figs. 2 and 4 of the drawings that anuprighty 50 extends from the lower end of the packer near the door up toa point immediately above the box 47, where it terminates. This upright50 passes through the sliding plate 48 in the same manner as the upright44. The upright 50 is pivotally connected to the framework of the packerat the pivotal bearing 51. The upright 50 is provided with two cams orinclines 52 and 53. The cam 53 is made integral with the upright, whilethe cam 52 is secured in an adjustable manner by the overlapping plate65, carrying the slots 54, through which the bolts 55 pass. The upright50 is actuated by the cams 52 and 53 coming in contact with ears securedon the movable platform 2 and standard 3. When the platform ascends ordescends, the ears thereon actuate the upright 50, and through thesliding plate 48 the upright 44 is either thrown into or out of contactwith the arm 46, secured to the plunger-beam. Thus it will be seen thatthe platform actuates the upright 50 automatically, which in turn movesthe upright 44 into engagementwith the arm 46 on the plunger-beam andthrough which construction a reciprocating movement is imparted to theupright 44, and through the crank-arm 45, which is pivotally secured tothe lower end of the upright 44 and the valve-shaft 41, the valve 40 inthe chute 39 is oscillated.

One of the standards 3 of the movable platform 2 is provided with an ear56, rigidly secured thereto, and which engages with the IOO IIO

cam 53 on the upright 50 on the ascent of the platform and moves theupright from the dotted lines in Fig. 4 to the position occupied by saidupright in full lines. This moves the upper end of the upright 50backward, and through the sliding plate 48 the upright 44, which ispivoted below the plate 48, is moved until the hook 45 on the upper endstands in the path and is actuated by the arm 46 on the plunger-beam 29.The platform '2 is provided with a second ear 57, which comes intocontact with the cam 52 on the lower end of the upright 50 and whichcontact moves the upright in `the opposite direction from the previousoperation, which also moves the upright 4:4 out of contact with the arm46. This last operation takes place when the platform has reached theend of the downward -movement, at which time the valve 40 is at rest andno material being discharged. When the platform has reached the bottom,the sack in which the packing has taken place is lled and not until thefull sack is removed and replaced by an empty one and `the platform hasrisen to the terminus of its upward movement, at which time the ear 56onl the standard 3 comes into contact with the cam 53, when the valve 40is again thrown into operation. It will be noted, however, that I in nowise interfere with the operation of the plunger, which in my packer isconstantlyin motion. Pivoting the upright 50 between. the cams 52 and 53provides a means for actuating said upright in both directions, as hasbeen previously described.

In Fig. 5 of the drawings I have shown the casing 26 secured to asliding plate 58, which plate slides in the ways 59, secured to theplatform 2. This construction provides -a means for removing said casingand replacing the' same by casings of various sizes or by substituting ablock that forms a base when I desire to pack into barrels. (See Fig.7.) Y
